用定语从句就是:I love the present you gave me very much.
不用的话: I love your present very much
I like your present very much.
加上you give me 之类定语从句是画蛇添足,不符合英语表达习惯。
I really like you to send a gift
I am also very happy to thank
这个比较完整
我真的非常喜欢你送的礼物
我很感谢 也很开心
I like the present that you give me very much.
I like your gift very much.
